They don’t have to be constant, they just have to change slowly enough to make statements with reasonable surety. For instance, the best indicator, believe it or not, of how busy a restaurant is going to be tomorrow is how busy it was on that exact same day last year.
Hmm, you might have a point. I’ll have to think that over. One of the things I was concerned with though was Mises’s claim that economics was a priori and not empirical. I hear the Ludwig Lachmann has a concept about “radical uncertainty.” I wonder what that’s about.
Similarly, people need to stay alive, need to be clothed, entertained, need transportation, and consume a million other things.
But I think Clayton raised a good point earlier about it not being simply about “clothes” but about what type of clothes. Given that people prefer different types of clothes, then a shift in the distribution of wealth would seem to shift the demand for types of clothes–unless the size of the economy would average things out.
But then if things don’t really change that much and people are largely the same, then wouldn’t that make calculation under socialism much easier as well?
To return to the topic: Many leading socialists back in the 50’s conceded Mises’s point on the economic calculation problem.
Which ones exactly (I honestly don’t know)?
Every attempt to communize completely, ie: farming, has led to mass starvation in the countries that tried it–China’s great leap forward, 20+ million people died.
I don’t support a China-style economy. I’m not very familiar with the famine, but it certainly seems that government policy was largely at fault. However, I’m not sure the calculation argument is the best means for explaining the disaster. The government pretty much forced “collectivization” on the people, didn’t base their plans on their input, and instead changed their farming methods based on the ideas of some crackpot. There also seemed to be an incentive to overreport farm production among local bureaucrats. And if it was because of the calculation problem, what does that mean? The demand for food changed? It didn’t change but the government stupidly thought that it decreased?
As for the famines in the Soviet Union under Stalin, it’s my understanding that those were intentional and not the result of a miscalculation.
I don’t believe that the collective farming in revolutionary Spain led to mass starvation. Actually, I’ve heard that it led to increased productivity. I suppose that is too short of a time to say much about though.
